移植实时Linux方案Xenomai到i.MX ARM64平台 (Enable real-time Linux Xenomai on i.MX ARM64 Platform)

    Xenomai is real-time framework, which can run seamlessly side-by-side Linux as a co-kernel system, or natively over mainline Linux kernels (with or without PREEMPT-RT patch). The dual kernel nicknamed Cobalt, is a significant rework of the Xenomai 2.x system. Cobalt implements the RTDM specification for interfacing with real-time device drivers. The native linux version, an enhanced implementation of the experimental Xenomai/SOLO work, is called Mercury. In this environment, only a standalone implementation of the RTDM specification in a kernel module is required, for interfacing the RTDM-compliant device drivers with the native kernel. You can get more detailed information from Home · Wiki · xenomai / xenomai · GitLab  

    I have ported xenomai 3.1 to i.MX Yocto 4.19.35-1.1.0, and currently support ARM64 and test on i.MX8MQ EVK board. I did over night test( 5 real-time threads + GPU SDK test case) and stress test by tool stress-ng on i.MX8MQ EVK board. It looks lile pretty good. Current version (20200730) also support i.MX8MM EVK.

    You need git clone https://gitee.com/zxd2021-imx/xenomai-arm64.git, and git checkout xenomai-4.19.35-1.1.0-20200818 (which inlcudes all patches and bb file) and add the following variable in conf/local.conf before build xenomai by command bitbake xenomai. 

XENOMAI_KERNEL_MODE = "cobalt" 

PREFERRED_VERSION_linux-imx = "4.19-${XENOMAI_KERNEL_MODE}"

IMAGE_INSTALL_append += " xenomai"

or
XENOMAI_KERNEL_MODE = "mercury"

PREFERRED_VERSION_linux-imx = "4.19-${XENOMAI_KERNEL_MODE}"

IMAGE_INSTALL_append += " xenomai"

If XENOMAI_KERNEL_MODE = "cobalt", you can build dual kernel version. And If XENOMAI_KERNEL_MODE = "mercury", it is single kernel with PREEMPT-RT patch.

The following is test result by the command (/usr/xenomai/demo/cyclictest -p 99 -t 5 -m -n -i 1000  -l 100000

Comments

Thank you Xiao, you are awesome. Xenomai is much better than PREEMPT RT kernel, with much lower latencies.

I'll test this !

Regards,

Laci

CPU isolation will help to improve the latency of Xenomai. Like:

1, Add isolcpus=2,3 in bootargs of uboot.

2, Run cyclictest  with option -a 2,3

 

Hi @xiaodong_zhang,

Any insights on xenomai v4.0 ?

Hi @r_trivedi123 

  I is busy on other project, and maybe enable Xenomai 4 on i.MX from Kernel 6.x when I'm available.

Hi @xiaodong_zhang ,

I understand. Could you provide or assist with any documents, steps, or references that might help us attempt it from our end?

Hi @xiaodong_zhang ,

First thank you very much for your post.

I have already apply your receipes, but when i run test, the error occur:

  • root@apalis-imx8-07106242:/boot# /usr/xenomai/demo/cyclictest -p 99 -t 5 -m -n -i 1000 -l 100000
    0"000.000| BUG in low_init(): [main] Cobalt core not enabled in kernel

I am try to apply the xenomai to imx8, (apalis-toradex-imx8qp).

The linux kernel is 5.4.193 and xenomai-v3.1:

Linux apalis-imx8-07106242 5.4.193-rt74-5.7.3-devel+git.49e4130e2197 #1 SMP PREEMPT_RT Tue Apr 11 21:14:29 UTC 2023 aarch64 aarch64 aarch64 GNU/Linux

Could you help me fixed it?

May i have any missing step?

Hi @xiaodong_zhang ,

 

After investigating, after i retry to build kernel with your batch, flash success to apalis imx8 board, with cobalt kernel, but when i run cyclelic_test, the kernel become to pannic.

so, i don't have any idea to apply the xenomai.

Please help,

 

 

Hi @HieuNong 

   I saw your board is Toradex Apalis not nxp mek board, so I suggest you may check device driver used by Apalis board if these drivers meet ipipe requirement. You can refer mek driver to modify your driver.

Hi @HieuNong 

  BTW, I saw your kernel version is 5.4.193, not 5.4.70 in my release package. Is some issues introduced when porting to 5.4.193? Would you double check it?

Hi @xiaodong_zhang ,

 

Thank you for you comment, exactly, it relate to driver and the linux kernel version.

I was trying to port the ipipe patched again, by download it from https://source.denx.de/Xenomai/ipipe-arm64/-/tree/ipipe/5.4.y/Documentation/admin-guide?ref_type=hea...

That is latest version work with linux kernel 5.4.180, even though it's not for 5.4.193 but it's still working with my board.

I was pass the panic kernel issue, and the cyclelic test is pretty good.

But, i still has the issue with driver, i will review it and modify the device tree or RTDM driver suitable with my board.

Thank you very much.

@HieuNong good news.

Hi @xiaodong_zhang ,

 

I was apply successfully the xenomai_v3.1 xenomai-5.4.70-2.3.4 patch to my board.

I very happy about that. Thank you for your post.

The solution is installing the board support package nearest with 5.4.70 kernel version.

In my IMX8 board, the suitable kernel version is 5.4.77.

After rebuild yocto, every thing work fine.

 

Hi @xiaodong_zhang 

Thank you for your post.

Following your guide, I've successfully installed Xenomai on Linux version 4.14.78. I am currently in the process of enabling the RTNet FEC driver and have adhered to the instructions provided.

Specifically, I added the line KERNEL_DEVICETREE += "freescale/imx8mp-rt-evk.dtb" to the file sources/meta-imx/meta-bsp/conf/machine/imx8mpevk.conf and similarly, KERNEL_DEVICETREE += "freescale/imx8mm-rt-ddr4-evk.dtb" to sources/meta-imx/meta-bsp/conf/machine/imx8mmddr4evk.conf to activate the rt_fec device within the Xenomai environment.

However, I have encountered a snag in my Yocto project; the corresponding .dts files seem to be missing from the freescale directory.

Could you please direct me to where I might find the imx8mm-rt-ddr4-evk.dts and imx8mp-rt-evk.dts files?

I apologize if this question has already been addressed previously. Your assistance is greatly appreciated.
